Abstract
We present a simple yet effective theory that predicts the existence of resonant radiation bands in the deep normal group-velocity dispersion region of a medium, even in the absence of a zero-group-velocity dispersion point. This radiation is evident when the medium is pumped with high-energy ultrashort pulses, and it is driven by the interplay between the Kerr and the shock terms in the nonlinear Schrödinger equation. Accurate experiments performed in bulk silica fully support the theoretical phase-matching condition found by our theory.
